Filter by:O2matic HOT is a further development of O2matic and is intended for home oxygen use with patients in need of long-term oxygen treatment (LTOT). O2matic HOT is a closed-loop system which on basis of signals from pulse oximetry titrates the oxygen flow to the patient. In this crossover trial patients are admitted for 24 hours twice. Once with usual fixed dose oxygen and once with oxygen titration by O2matic HOT.
This is an open (non-blinded), single-arm, clinical trial to assess the efficacy of daily use of a high-flow nasal cannula (HFNC) device in patients with moderate to severe COPD, in addition to standard care, in reducing the amount of COPD exacerbations over a one-year period. Once enrolled in the study, all subjects will be asked to undergo a baseline walking test to measure pulmonary function (6MWT), verify their personal and medical history (demographics), as well as fill in some questionnaires regarding their COPD and its symptoms (SGRQ-C, CAT). All subjects will then receive their own AIRVO2 device, as well as training and instructions on how to use the device at home. Subjects will use the MyAIRVO2 device daily for the following 12 months. Follow-up visits will occur five times over the 12-month study period and will be similar to the baseline visit. Additional data will be collected by the study team for each subject from their electronic medical record during the 12-month study enrollment period. Only information regarding COPD-related medical and/or pharmacy costs, specifically to measure the amount of COPD exacerbations experienced by each subject, will be reviewed and recorded.
This is a pilot observational study during which the investigators will conduct a longitudinal assessment of air trapping (with up to 2 visits) in 40 patients with COPD and variable degrees of air trapping and 20 healthy controls using ARIA. The investigators will characterize the clinical phenotype of the subjects by administering health and symptom-based questionnaires and obtaining lung function testing at rest and during exertion, and will then correlate and validate the ARIA-based indices with those of the more traditional physiologic measures of static and dynamic air trapping.
The purpose of this study was to evaluate the effect of ION-827359 on forced expiratory volume in 1 second (FEV1) in participants with mild to moderate COPD with CB.
This study will test whether daily use of azithromycin will reduce the rate of exacerbations and improve lung ventilation and perfusion assessed by XE-MRI. The sensitivity of XE-MRI to detect COPD progression will be compared with standard clinical assessment measures including standard lung function tests, 6 minute walk test, and patient reported quality of life.
The purpose of this study was to determine whether potentiating the cystic fibrosis transmembrane conductance regulator (CFTR) with QBW251 in subjects with COPD would be efficacious with regards to reducing lung and systemic inflammation and bacterial colonization as potential drivers of airway obstruction, airway destruction, remodeling and exacerbations. Furthermore, this study provided supportive data to investigate the relationship of COPD phenotype and the response in small airway structure, function, mucus load and spirometry indices as well as in improvement of overall COPD symptoms and quality of life.
The study is intended to assess the relative bioavailability of 2 different abediterol nebulised formulations (test) and the dry powder formulation (reference). The study results will provide information on the pharmacokinetic (PK) profile following use of the 3 devices to be used in further clinical development.
This is an 8-week randomized controlled trial to help address health, resilience, and well-being. Participants are randomized into either a health education group or an arts-based health education group. Both groups will attend for 8 weeks and various study assessments will be conducted in order to measure the experience and impact of the program. Anyone 18 years and older with a chronic health condition (for example, diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disorder, asthma, weight, anxiety, depression, cardiac, arthritis, multiple sclerosis, and many more) are eligible to participate.
Many exercise tests are commonly used to evaluate the changes of exercise tolerance following rehabilitation programs in patients with chronic respiratory diseases. Among the tests (6-MWT, incremental test, ...), the literature seems to indicate that endurance time is the most responsive parameter for detecting and quantifying changes in exercise capacity following a rehabilitation program. Although its clinical interest is undeniable, the endurance shuttle walking test is rarely used because it requires the prior performance of two incremental shuttle walking tests to determine the walking speed imposed on the patient. In this protocol, we propose to test a Walk-Time Limit Test (WTLT) derived from the 6-minute walk test (6-MWT) and based on the average walking speed achieved in this test commonly used in the follow-up of patients with chronic diseases. TTLM validation would improve the functional assessment of patients with chronic diseases while limiting the number of exercise tests.
In COPD patients with chronic hypercapnic respiratory failure, the prognosis is poor and the treatment with non invasive ventilation is actually well established. However the best mode of ventilation is not well known. In severe COPD patients various disorders of respiratory mechanics result in insufficient ventilation, which can be life-threatening or create NIV discomfort. The main characteristic of these disorders is a cyclical closing of small airways that can limit an expiratory flow and provoked some fluctuations in flow curve. To our knowledge, the management of dynamic hyperinflation seems to play an important role in explaining the effect of the NIV. Few studies have examined the effects of the machine's adjustments on dynamic hyperinflation. The main objective of this study is to analyze the impact of specific ventilatory modes supposed to reduce the dynamic hyperinflation on the hematosis, by studying transcutaneous pressure of carbon dioxide, in severe hypercapnic COPD patients ventilated by NIV. Two modes of ventilation will be compared. First one is an algorithmic mode developed by the company Löwenstein (AirTrap Control, Trigger Lockout and the Expiratory Pressure Ramp). The second one is a standard algorithmic mode, used in the same ventilator. These two ventilatory modes will be evaluated in each patient, during two consecutive nights in current living conditions at home.
